HAROLD r. vosn, or new YORK, N. Y.

VENTILATOR.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, HAROLD P. Vosn, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Ventilators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to window ventilators, and has reference more particularly to that type which comprises a deflector or wind-guard adapted to be set in position along the window-sill and acting in connection with the partially opened window to admit the air into the room in an indirect course.

The object of the invention is to provide a ventilator which may be quickly and easily adjusted for application to the windowframe at will, the deflector of the ventilator being for this purpose provided with means which directly engage the window-frame, preferably the jamb.

Further objects of the invention are to provide a simple, inexpensive and eflicient ventilator so constructed that the parts may be collapsed or folded into compact form for packing and transportation; and may be readily adjusted for use.

With these ends in View, the invention consists of certain features of construction which will be hereinafter fully described and the novel parts set forth in the claims, reference being had to the accompanying drawings showing the form of the device which I prefer to adopt.

In the accompanying drawings: Figure 1 is a front elevation showing the ventilator in position. Fig. 2 is a horizontal section on the line 22 of the preceding figure. Fig. 3 is a vertical section on the line 33 of Fig. 2. Fig. 4 is a plan view of the ventilator showing the parts collapsed or folded. Fig. 5 is a perspective view of one of the supporting stays.

Referring to the drawings: The deflector comprises two sections 1 and 2 of corres onding dimensions, and composed preferably of light thin boards, or other suitable material, placed face to face and connected telescopically so that the deflector as a whole may be adjusted longitudinally to difl'erent widths, or may be collapsed or folded into com act form.

cans are provided at the outer ends of the deflector sections 1 and 2, for supporting the deflector in position by engaging said means with the windowframe, as at 9. Said supporting means are preferably in the form of stays 10 and 11, which are preferably secured to which is to rest upon the window-sill, so that the lower sash may be raised or lowered to provide an air inlet opening of variable size beyond the deflector.

The stay 10 comprises a bracket or clip 12 for attachment to the deflector, a stay-member 13 connected with the bracket, and an attaching or grip-member 14 for engaging the window-frame, which grip-member is carried by the stay-member. stay-member 11 comprises corresponding parts 15, 16 and 17. The brackets or clips 12 and 15 are preferably formed of metal plates bent into U-form so that they may be frictionally engaged over the edges of the deflector, thereby providing for their adjustment longitudinally of the deflector, and their removal therefrom when desired. The stay-members 13 and 16 are, in the present instance, in the form of wire arms pivotally attached to the clips in such manner that they may be swung horizontally to different positions, or may be folded down on the deflector for the purposes presently to be described. The pivotal connections with the clips are conveniently effected by bending the ends of the arms at right angles and loosely engagin the bent ends in bearing sockets 011 the clips. The grip-members 14 and 17 are each formed, as shown more particularly in Fig. 5, of a section of spring wire bent on itself to form coils 22 and jaws 23 and 24;, the ends of which latter are extended in opposite directions to form engaging fingers 26. By springing the jaws together, the engaging fingers may be passed in between the beads of the window-frame,

so that when the jaws are released, they will spring outwardly and cause the fingers to Patented Aug. 16, 1910. Application filed November 30, 1909. Serial No. 530,624..

that edge of the deflector j The other engage the beads and thus effect a secure at tachment to the frame. These grip-members are connected with the stay-members by passing the wire arms of the stay-members through the central side coils, the result being that the pressure of the coils will hold the grip-members on the arms, and will at the same time permit the members to be moved to difierent positions longitudinall also permit the grip-members to be swung coils and between the j of the arm, and will around the arm as an axis. This admits of the adjustability of the grip-members to beads and window-frames of diflerent forms and dimensions, and also provides for the folding down of the grip-members alongside the deflector when the arms are likewise folded for packing or transportation.

In adjusting the ventilator for use, the sections 1 and 2 are slid out to the proper distance for the windowframe to which the ventilator is to be attached, and the staymembers 13 and 16 are moved outwardly to a position at substantially right angles to the sections. The grip-members 14 and 17 are now swung outwardly upon the staymembers and the ventilator secured in position in the window-frame by engaging the fingers of the jaws between the beads of the sash grooves, as shown in Fig. 2. When thus adjusted, the deflector will be securely and firmly held in upright position at the inside of the lower sash, and by raising the sash to the proper height, the air in entering the room will flow beneath the sash, then upwardly between the same and the deflector, and will then be distributed uniformly, and in this manner prevent objectionable drafts. In the removal of the device, the fingers of the grip-members are disengaged by pressing the jaws inwardly toward each other, whereupon the arms carrying the grip-members are swung inwardly toward the deflector sections. In folding the device for packing or transportation, the two sections are collapsed or slid inwardly on each other, the stay-members folded down on the sections, and the grip -members likewise folded down. In this form, the device occupies little space and may be conveniently and economically handled in packing and shipment.

While in the accompanying drawings I have shown my invention in the form which I prefer to adopt, it is manifest that the in vention is not limited in its specific details, except in so far as such limitations are specified 1n the claims.

Having thus described my invention, what I claim is 1. In a ventilator, the combination with a deflector of stiff material adapted to extend from side to side of a window frame with its lower edge resting 011 the sill thereof, of a pivoted support for said deflector adjustable longitudinally along the latter, and adapted to be swung into engaging relation with said window frame at will.

2.
